According to the Western logic of human body, the body needs enhancing of its capacities. (Compare to the Eastern view, according to which everything one needs for breaking down the circle of samsara, is already inherently present in human.)
For the West, looking inside is but a waste of time, and evolution is too long a process.
“We could not wait for favors from nature, we should take them from her,” was one of the slogans of Soviet industrialization, and the Soviet project was taking to the edge a world-wide trend, profoundly Western in its drive to redefine the environment, recreate the planet, and establish the paradise on earth.
The Western Capitalism was built on the Protestant principles, and the Soviet Communism was built on the Ortgodoxy, a branch of Christianity which has long stressed the priority of collective forms of need, aspiration, and intention, over individual; public over private, exterior over interior, architecture over design, utility over comfort, praxis over theory, necessary over excess and unneeded; despised luxury and praised asceticism; took with suspicion any kind of hidden meaning; dismissed complexities of inner life like idle self-indulgence, and so on.
Machines are tools which are in full command by humans, but since they enlarge the might of bodies, and thus become parts of bodies and transform living organisms into cyborgs, they are simultaneously the instruments which enslave us. The relations of the body and its prostheses are characterized by interdependence. We are from birth initiated into and grow in networks of tools which render us powerful and powerless at the same time.
